It wouldn't really surprise me if the average kindergarten teacher (or just adult) had no idea how e.g. an air conditioner or an elevator or one of those emergency flashlights that you can power by shaking or any number of other everyday things works.

Are you asking me to believe that the educational system underserves kindergartners because the average kindergarten teacher can't provide an education on your narrow technical interest?

The responsibilities of the average kindergarten teacher probably include 1) making sure your kids don't swallow glue, and 2) making sure little johnny doesn't throw another tantrum.
